Severe Complications With Eustachian Tubes
Tinnitus

Tinnitus, ringing in the ears, occurs when there is a blockage in the eustachian tubes. It affects about one in five individuals and is often a symptom of an underlying condition, though not always. It has been known to worsen with age and improve with treatment. When the eustachian tubes are blocked, it may cause ringing in the ear instead of the individual being able to hear outside noise. Also known as a circulatory problem, tinnitus may result in mild hearing impairment or a type of head noise.
Eustachian Tube Dysfunction

Eustachian tube dysfunction occurs when the eustachian tube does not open properly or is blocked. When this occurs, air cannot get through to the middle ear, which causes pressure on the external side of the eardrum and pushes it inward. Due to increased pressure, the eardrum becomes tense and does not vibrate as well when hit by sound waves. This causes a loss of hearing or a muffled sound, pain in the eardrum, and a feeling of fullness in the ear.
